I. Product Introduction

The Flange Connection Globe Valve is a versatile, linear motion valve widely applied in industrial fluid control systems, designed for on-off regulation and throttling of medium flow. Featuring a reliable flange connection mode, it ensures easy installation, disassembly, and maintenance, making it suitable for a broad range of industrial scenarios including chemical processing, water treatment, petroleum refining, and HVAC systems.

This valve series covers three basic structure forms: straight-through, direct-flow, and angle type, with nominal pressure ranging from PN0.6 to 1.6 MPa and nominal diameter spanning DN15 to DN350 (DN15 to DN300 for angle type). The fully lined design (with FEP, PCTFE, PFA, or PO lining options) enhances its corrosion resistance, enabling it to handle corrosive media such as acids, alkalis, and salts effectively. Available in manual, pneumatic, and electric operation modes, the valve can be flexibly matched with different control systems to meet both local and remote control requirements.

II. Product Features

Stable Flange Connection

Adopts standard flange dimensions (compliant with HG/T20592 or customized by contract), ensuring tight sealing and strong load-bearing capacity. It effectively prevents medium leakage and adapts to various pipeline connection requirements.
Diversified Structure Forms

Straight-through, direct-flow, and angle type structures are available to suit different pipeline layouts:
- Straight-through and direct-flow types are suitable for horizontal pipeline systems, reducing flow resistance and improving throttling performance.
- Angle type is ideal for pipeline turning scenarios, saving installation space and reducing pipeline elbows.
Excellent Corrosion Resistance

The fully lined structure uses high-performance corrosion-resistant materials (FEP/F46, PCTFE/F3, PFA, PO) for the lining and seat, isolating the medium from the valve body and internal components, and ensuring stable operation in corrosive working conditions.
Multiple Operation Modes

Supports manual, pneumatic, and electric actuation to meet diverse control needs:
- Manual operation: Simple structure, low cost, suitable for local control scenarios with low frequency of operation.
- Pneumatic operation: Fast response speed, high control precision, applicable to automatic control systems with centralized regulation.
- Electric operation: Realizes remote control and intelligent regulation, easy to integrate with PLC, DCS and other control systems.
Standardized Design and Manufacturing

Complies with national standards such as GB/T12233/GB/T12235 for design and manufacturing, ensuring product quality and interchangeability. Pressure test strictly follows GB/T13927 to guarantee safe and reliable operation under rated pressure.
